Commonly used tools for removing snow include hand tools such as shovels, mechanical devices such as shovels and rotary blowers, and snow removal channels that drain large amounts of water into snow drifting channels with slopes suitable for snow removal. There are facilities that input and transport snow, as well as truck transportation from specific urban areas to snow storage areas, snow melting methods using hot water, snow melting agents, etc.
Hydraulic transport, in which snow and water are mixed and transported using rotary or reciprocating pumps, has been proposed and researched, but it is still far from being put to practical use.

With means such as shovels and shovels, it is not possible to secure even a narrow living area in areas with extremely low amounts of snow removal, and with means of transportation such as trucks, it is difficult to secure a transportation route and it is difficult to secure continuous transportation routes. Since snow cannot be removed, the amount of snow removed or removed is larger than the former method, but it is difficult to say that it is an effective snow removal method in terms of economic efficiency. In addition, the method of using snow-drifting ditches requires a large amount of water and requires a large slope for the snow-drifting, making it impossible to use existing sewer pipes and other equipment, and therefore rotary pumps The conveying distance must be ensured by repeatedly letting the snow that has been raised to a high place flow down naturally, and the cost of equipment is enormous, and this method cannot be used everywhere. Furthermore, the unfinished method of mixing snow and water and pumping it through a primary pump such as a rotary pump has problems such as snow particles adhering to the pump blades, dirt and stones contained in the snow, plastic bags, strings, etc. etc.,
Not only does this reduce the pump transport efficiency, but also the above substances cause clogging, making it impossible to operate, and in the snow-water multiphase flow, snowflakes adhere to each other and grow large, which causes clogging, making it difficult to put into practical use. It was sexually unsatisfactory.

The present invention is basically similar to the proposed snow and water mixed flow method in that it utilizes water, but it does not directly use a primary pump and therefore eliminates snow adhesion to the blades. The object of the present invention is to provide a snow conveying and discharging device that can perform extremely economical and efficient snow removal without entanglement of dirt and debris, and without causing snow masses to bond and solidify with each other in a conveying pipe. It is.

FIG. 4 shows a miniaturized version of the device shown in FIG. 2 so that it can be kept at home. A flow pipe is connected to the discharge port 82 of a self-propelled rotary blower 71 via a bellows pipe 12 that allows left and right swinging. The starting end of the discharge cylinder 51 corresponding to the passage 5 is connected, and the water jet nozzle 4 is installed toward the center of the discharge cylinder 51, and the radial left and right sides of the discharge cylinder 51 and the main body of the self-propelled rotary blower 71 are connected. The structure is such that the two cylinders 13 are connected by two hydraulically extending cylinders 13. This depends on the amount of extension of the two cylinders.
The tip of the blower is moved vertically or horizontally, making it suitable for blowing away snow over a wider area than is possible with a normal rotary blower.

It is better to share the crushing function. Furthermore, it is best to make part or all of the supply flow pipe passage 5 a bendable pipe in order to facilitate arbitrary selection of snow removal locations. Furthermore, the high-pressure water jet nozzle 4 may be installed at a predetermined position in the flow pipe passage 5 at an angle that has an injection component force in the discharge direction; There may be multiple circumferences around the center 5 and along the inner wall surface of the flow pipe, and these are determined by the material, diameter, distance, etc. of the flow pipe passage 5. It goes without saying that the configurations shown in each embodiment can be used in partial combination with the configurations of other embodiments.

The device of the present invention supplies high-pressure water made high by a primary pump or the like to the water jet nozzle, and also directly supplies and drops the transported snow into the open snow supply space. The snow that has fallen between the opposing ends of the starting end of the flow pipe passage is crushed and pushed into the flow pipe passage while being pulverized by the water jet sprayed from the water jet nozzle. At this time, air enters along with the snow, and snow is suspended in the jet water in the flow pipe passage, and there is a flowed material with an air layer interposed between them. Due to their nature, the fine snow particles in the pipe tend to attract and couple with each other, but they are disturbed and prevented by the jet flow velocity and the pulsation of the intervening air layer, so that they float on average in the flow pipe passage. The liquid is gradually fed under pressure toward the discharge port.

The device of the present invention is for simultaneously crushing the snow that has fallen to the bottom of the open snow collecting container and forcefully feeding it into the flow pipe passageway. By simply throwing in the collected snow, it is possible to extremely efficiently transport and discharge snow to a predetermined location at a distance.

Furthermore, the device of the present invention has a structure in which high-pressure water supplied from a high-pressure water supply source using a plunger pump or the like is forced to rush into the flow pipe passage as a jet from the bottom space of the open snow collection container. Therefore, due to the collision of the jet jet and the joint action of suction and press-fitting, the snow is broken into pieces smaller than the diameter of the flow pipe passage at the starting end of the flow pipe passage and enters the flow pipe passage extremely smoothly. As a result, the snow is pumped through the flow pipe passage without passing through the pump. Therefore, there is no need for a snow removal slope, and even if the snow to be sucked contains debris such as debris, plastic bags, ropes, strings, etc. As long as it is, it is possible to perform pressure feeding without any problems, and it is possible to eliminate the possibility of snow adhering to the moving parts of the pump body and solidifying it, or the above-mentioned dust getting entangled, reducing operational efficiency or causing a situation where operation is impossible. A large amount of snow removal process is achieved.

Furthermore, since it has a simple structure by combining the water jet nozzle with the piping body and the snow collecting container with a simple structure, the equipment cost is not only low, but the piping equipment etc. are also easy, so it can be adapted to each region. This makes it possible to install snow removal equipment, which has the effect of greatly contributing to eliminating snow pollution in areas that experience heavy snowfall every year.
